Facebook no longer works on Firefox!
Hi All! For a a few weeks when I loaded Facebook via FF I got the message 'your browser is no longer supported by facebook'. Yesterday it just stopped working but defaulted to a basic facebook screen bit with all the info missing left and right, basically just the messages. Be grateful if there is a fix for this please! Many thanks,
Duncan

You can check the Web Console (Tools -> Web Developer) for messages about blocked content and about the presence of mixed or unsafe content.
You can check the Network Monitor to see if content is blocked or otherwise fails to load.
If necessary use "Ctrl+F5" or "Ctrl+Shift+R" (Mac: Command+Shift+R) to reload the page and bypass the cache to generate a fresh log.
Boot the computer in Windows Safe mode with network support to see if that has effect in case security software is causing problems.

You can remove all data stored in Firefox for a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History -> Show All History" or "View -> Sidebar -> History").
Using "Forget About This Site" will remove all data stored in Firefox for this domain like history and cookies and passwords and exceptions and cache, so be cautious. If you have a password or other data for that domain that you do not want to lose then make sure to backup this data or make a note.
You can't recover from this 'forget' unless you have a backup of involved files.
If you revisit a 'forgotten' website then data for that website will be saved once again.
You can try to login to Facebook in a New Private Window.
You can check for issues with location storage (indexedDB).
This could be a problem with local storage and possibly running this command in the Web Console to clear storage as posted in bug 1569296 might fix it.
- localStorage.clear()
- "3-bar" menu button or Tools -> Web Developer
